GERNT, TENNESSEE SAW 1 FILER Application fiIedQ'February ZS, 1925. "Serial No. 12,313.

"My invention relates to new-and useful improvements ina-saw filerxadapted to file all :kinds ofchisel tooth,'circular, and bandisaws,

the-principal object of the invention residing 51in theg provision of a filer'ofthe. character ,described in which afile of well-known or :common construction may be used-and operwatedby hand,- the file'being' detachably connected to its carrying? frame, the frame being mountedfor-swmging: movement to 1 engage :the file with the teethofthesaw. and the file :beingrconnected' to the carrying frame for angular adjustment to secure the proper pitch .or engagement i with the teeth.

Another object ofvthe invention resides in i the provision of a supporting frame i which isadapte'dnto beset-over the saw and supiported thereby, said' frame having yieldable and adiustablearms which engage the. teeth of the saw andubearings' forsupporting the i :parts; described in the following specification, and illustrated ;in uthe 1 accompanying drawings, and while'I have illustratedand "described. the-preferred embodiments of the invention as theynown-appear tome, it will be understood that'suchchanges may :be made as willi fall within thescope of theappended claims.

.In the drawings =Adenotes generally the supporting frame and B the file carrying frame mounted on the supporting'frame for slidable. and swinging movement. The supporting frame includes the inverted U shaped members 1. and 2 which are adapted to fit over the sawblade as more particularly illustratedin-FigsQ and 3 of thedrawings, the saw blade indicated at 3 being in the instance shown as of-a circular type mounted.

-on= and carried by the shaft or mandrel 4:.

Secured to the members 1 and flare the hori- 'izontal framesb which are supported by the diagonally extending'brace bars 6, the upper ends of the brace bars being connected at? to the frames and the lower ends being con :nected at 8. adjacent the lower ends of the members 1 and 2. The members 1 and 2 are -connected together by the horizontal bars 9 and between these bars 9 and the outer ends of the frames 5 are the diagonally extending braces was more particularlyshown in Figs.

. land 30f the drawings. Secured to the outer faces of each of the members 1 and2, on each side. of the slot-formed in the members, are the plates or auges. 11, more particularly illustrated in? ig. .4 of the drawings, and each of the plates orgaugesll is provided with the vertically spacednotches 12 into which the bolts 13 are adapted to pass the bolts receiving the nuts-14 andwashers 15.

.The boltsand nuts secure the plates or gauges to the members 1 and 2 and it can readily be appreciated that through means of -.the inotches 12 the plates may be adjusted to vary; .the distance between the inner vertical edges thereof so as to engage the side faces of saw -blades-of varying thicknesses. As quite clearly illustrated in Fig. 4 of the drawings the inner vertical'edges of the plates or gauges .11 will overlie theslots formed in the members-1 and 2. Secured to the outer face of the member 2, by means of the bolts 16 and nuts 17, is the bracket 18 having the transversely extending rod 19, said rod being in i the form a threaded bolt receiving the nut '20as more particularly illustrated in Fig. l of the drawings. This rod or bolt 19 sup-' ports the arm or plate 21 through means of the upwardly extending U-shaped bracket or hearing through which the rod or bolt passes as shown more particularly "in Fig. 2 of the drawings, and it canreadilybe appreciated that'the arm or plate may be swung to varione anglesto'properlyengage the saw teeth and will be held at such adjusted'position' when the nut is tightened upon the bolt it being appreciated that the bracket 18 isof sufficient resiliency to allow the arms thereof,-

f jtends, to engage the ends of the bracket or between which the bracket or bearing 22 exbearing 22. 'Securedto. the memberI by means of'the bolts 23, or other suitable fasten er's,is the arm or plate 24 which is adapted to engage the saw teeth as more particularly- I illustrated in Fig. 2 of thedrawings; This 1 arm orplate 24 has the upwardly extending member 1 1. Secured between the upwardly portion 25, the horizontal portion 26, and the vertically extending portion 27,-the bolts 23 passing through said vertically extending portion 27 to secure the arm or plate to the extending portion and the vertically extending portion 27, and beneath the horizontal portion 26, by means of the bolts 28, isthe bearing 29 for a purpose to be later described,

the bearing being preferably formed of two blocks or plates as more particularlyillustra-ted in Fig. 2 of the drawings. The arm or plate 24'passes through the slot formed in themember 1 and is provided on each side edge with a notch 30 to receive the Vertically extending edgesof themember'l adjacent the 7 V 7 slot. The arm; or plate 21 is provided in each side edge with a notch31 to receive the ver-' tically extending edges of the member 2 adj a- Supported on the outer'end ofeach-o'fthe" T '45 cent the slot therein,thearm or plate extend-' ingfthrough the'slot as is quite clearly shown.

horizontally extending frames 5 is a'vertical to the horizontal frames by means of the 1 bolts 33 and nuts 34.- V

" 'zontally extending rod 35 which is supported by the posts or standards 32 by passing the 55 file will engage the teeth of the saw and then The file carrying frame B includes the hori rod through the horizontally extending openings formedadjacent the upper ends thereof,

r the rod also passingthrough thebearing 29. Therod 35 is mounted. for both slidable and rotatablemovement and secured to the rod between the posts' or standards 32 are the arms 36 which .haveopenings through which i j the rod passes. The arms 36 are secured to the rod 35 by the screws or bolts 37 and it 7 can readily be appreciatedthat the armsmay be adjusted angularly orlongitudinally upon the rod 35. The arms are connected together by means of the rod 38 and carried by the arms is the horizontal rod 39 which passes through openings formed in the arms and it is held in itsadjusted positions by means of the bolts or screws 40, which pass through the ends of the arms. When the'screws or bolts 40 are loosened the rod 39 may be longitudinally adjusted or rotated'relative tothe arms. Secured upon the rod 39 are the file clamps which include the upper members 41, of the shape shown more particularly in Fig.2 of the drawings, said members 41 having an 7 opening therethrough for the rod 39 and held in position by means of the bolt-orscrew 42; By loosening thebolts or screws, 42 the members 41j maybe adjusted lo-ngtudinally of the rod 39 or angularly adjusted relative thereto; Secur edto themembers 41 by means of the bolts '01 screws 43 .aretheplates 44 and the 1645 is adaptedto be secured between the members. 41 and plates 44 as more particularlyillustrated in Figs, 1 and-2 of the drawings. The file 45 is of common-or well-known construction provided with a hand hold 46 at one end. Securedfupon the rod 39Iis a' dial- 46 and securedxto one of the-fileclamps, adjacentthe. dial, is a pointer 47. The dial will'be suitably' graduated and cooperates with the pointer-'47 to indicate the degree ofadjustment ofthe file. From the above detail description-fit is thought that the manner of usin'g'my im proved form of filer will be apparent. The

supporting frame is adaptedto be positioned over the saw'blade'as shown in the'drawings andis supported entirely by the saw blade itselfbyiengagement of the plates or arms 21 upon theteethof the blade. The blade will extend up into the slots formedin the members land 2 and the gauge or plate members 11- carried by the members land 2 will be adjusted to. engage the side faces of theiblade.

The'file-is secured in the clamps and may be angularly adjusted upon the-rod139 by loosening the screws orbolts 42 sothat theff'ace of the fileiwillproperly engage the saw teeth. vThe-file frame maybe swung as'a unit by rotation of the rod 35 in the posts or standards 32 andthe arms 36 of the file carrying frame maybe adjusted either longitudinally or angularly with respect tothe rod 35 by loosening the'bolts-or screws 37. With the file carrying frame "sw ung downwardly the saw whioh remains mounted upon its 1 shaft or mandrel and the teeth are; successively brought into position for'operation up'on by the file by rotating the saw. othertypes of saws are to be operated upon they may be mounted upon or clamped to suitable supports but in all instances the supporting frame of the filer is mounted directly upon the saw blade.

From the above it will be seen that I have provided a filer in which the ordinary or common form of file may be used and 0perated entirely by hand, the filer being supported directly upon the saw blade and the file mounted for various adjustments being free for swinging movement for raising out of engagement with the saw teeth or lowered to engage the teeth. The plate or arm 2 which engages the saw teeth is of sufficient resiliency'to yield and assume the proper level for engagement with the teeth of different types of saws. The plate or arm 21 is readily adjustable to properly engage the teeth of different types of saws. By means of the pointer 47 and dial 46 an indication of p the adjustment of the file may be secured.

Having fully described my inventionwhat I claim as new and desire to secure by Letters Patent is:

1. A saw filer including a pair of spaced members having slots to receive the saw, a horizontal frame carried by said members, a yieldable arm secured to one of the members, a bracket secured to the other of the members, a yieldable arm suspended from the bracket and connected thereto for swinging movement, said arms extending longitudinally of the edge of the saw and engageable therewith at spaced points, a file, and means for connecting the file to the frame for sliding movement and for engagement with the teeth of the saw.

2. A saw filer including a pair of spaced members having slots to receive the saw, a horizontal frame carried by said members, a ieldable arm secured to one of the memers, abracket secured to the other of the members and having spaced arms, a bolt ex tending through the arms of the bracket and supported thereby, a yieldable arm suspended from the bolt and adapted for swinging move ment, said yieldable arms extending longitudinally of the edge of the saw and engageable therewith at spaced points, afile, and means for connecting the file to the frame for sliding movement and for engagement with the teeth of the saw.

In testimony whereof I hereunto affix my signature.
